Static Electricity. Basic principles of electrostatics are introduced in order to explain how objects become charged and to describe the effect of those charges on other objects in the neighboring surroundings. Charging methods, electric field lines and the importance of lightning rods on homes are among the topics discussed in this unit.

The Meaning of Force. A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction.

For example, consider the addition of the same three vectors in a different order. 15 m, 210 deg. + 25 m, 300 deg. + 20 m, 45 deg. SCALE: 1 cm = 5 m. When added together in this different order, these same three vectors still produce a resultant with the same magnitude and direction as before (20. m, 312 degrees). A measure of the ability of a substance, or more generally of any physical system, to transfer heat energy to another physical system. Any of various standardized numerical measures of this ability, such as the Kelvin, Fahrenheit, and Celsius scale. As mentioned, the first two bullet points have rather obvious meanings.
